I’m into some freaky stuff. Just ask @NMEGaryOak
Completely agree is like saying Bastia can Backfire because it mess up your entrance passives it’s just crazy you build arround it so there is no backfire
“Unlikely” is the phrase LemonSqueezy said and I think that’s the correct one. You can only play Lemon in the end-game so you can’t rely on exactly what state your side of the field will be in. Even if you play lots of sleep immunity before Lemon they could be killed off; or your opponents have their monsters poisoned and you weren’t able to remove it so all it did was sleep your own team.
While it’s unlikely it will backfire, it’s quite common you meet some kind of counter.
Obviously it’s an incredibly powerful entrance that’s worth considering as a “first entrance only” type passive but I think compared to the other passives we’ve seen get unmovable those ones did have more reliable value. There’s an argument to be made that this entrance has enough counters it doesn’t need any further restrictions put in place (beyond the 250s from start of battle).
